Floating visual displays, ultrafast imaging and far-UVC light: the June 2020 edition of Physics World is now out – Physics World

Physics

The June 2020 issue of Physics World covers acoustically levitated displays, how far ultraviolet light could tackle viruses and working towards ultrafast imaging in medicine.

Hovering 3D images are the stuff of science fiction. Just think of R2D2 projecting a message from Princess Leia in Star Wars, or perhaps Iron Man designing his latest tech in Marvel movies.

But in a Faraday cage at the University of Bristol in the UK, fiction is becoming reality with the help of some speakers and polystyrene balls.

As Michael Allen finds out in the cover feature of the June 2020 issue of Physics World, which is now out in print and digital formats, floating visual displays created using acoustically levitated particles could lead to galleries of singing heads, and even to advances in contactless manufacturing.
